28 florney- Patented Get. 17, 1933 UNITED STATES PATENT OFFICE .2 Claims.

This invention relates to an improvement in the means for locking garment fasteners and more particularly to those of the type commonly known as zippers, and the principal object is to effectively lock or secure such fasteners against coming apart accidentally, and to that end I provide a locking lever for a safety latch that must first be actuated before the fastener can be opened, thereby assuring the person wearing a garment to which the fastener is attached that it will not come apart until the lock of the safety latch is properly manipulated.

Another object of the invention is to provide a locking lever for a safety latch for a fastener so that when the latter is used to close the inlet to a money pocket, bag or purse, it will be effectively locked so the fastener will require a noticeable manipulation to release it before the fastener can be opened, and it is obvious that such a lock for a safety latch will be of great use in protecting valuables against pick-pockets and like thieves.

A feature of invention is shown in pivotally mounting a locking lever on a pivotally mounted latching lever in position to hold the latter in a relatively fixed position until the locking lever is turned to a position to permit pivotal movement of the latching lever.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

The accompanying drawing illustrates the invention, in which:

Figure 1 is a fragmental view of a garment fastener with a locking lever connected to a latching lever that is constructed in accordance with this invention, parts indicated semi-diagrammatically.

Fig. 2 is a view analogous to Fig. 1 with parts omitted.

Fig. 3 is a view analogous to Fig. 2 with the locking lever moved to a latch releasing position. Fig. 4 is a side view of the locking lever detached from the latching lever.

Fig. 5 is a section through the locking lever on line 55 shown in Fig. 4..

Fig. 6 is an enlarged fragmental semi-diagrammatic plan view of a garment fastener with the safety latch in a locked position, and part in section on the line 66 of Fig. 1.

Fig. 7 is an enlarged semi-diagrammatic view of the garment fastener slide with both levers 9 in. a locked position.

Fig. 8 is a view analogous to Fig. 7 showing the locking lever moved to an' unlocking position.

Fig. 9 is a view analogous to Fig. 7 with both levers in unlocking position.

Fig. 10 is an enlarged front view of my fasten- J0 er detached from a garment and by full lines showing my latching and locking lever in a locked position and by dotted lines in an unlocked position.

Fig. 11 is a central vertical section on the line 11-11 Fig. 10, with the latching and locking levers in a locked position and also indicating by fragmental dotted lines how the latch lever can be moved in an arc to release the fastener when the locking lever is in an unlocked position.

Fig. 12 is a central vertical section on line 12-12, Fig. 11, showing the inside of the slide with a slot therein for the tooth of the latching lever; and by dotted lines diagrammatically indicating the locking members and the tapes and cloth to which they are secured.

My locking lever 20 can be operatively secured to any of the well known types of garment fastener, but for the sake of brevity it is shown and 30 described as attached to only one of them.

Practically all of the garment fasteners include top stops 21, bottom stops 22, looking members 23 and 24 that are properly secured to tapes or cloth strips 25, a slide 26 and a slide latch 27 pivotally secured to the slide which has the top end portions of its front and back parts integral with the union 126 that on its upper end has the usual eyelet 226 for a hand ribbon not shown; and, all of these parts are old and need not be shown or described in complete detail.

In the first instance I pivotally connect my locking lever 20 to the latching lever 27 by a pin 28, and provide an extension 29 at one end of the locking lever that is at right angles thereto that, when in the position shown in Figs. 1,

2, 6, 7, 10, 11 and 12 engages the slide 26 and prevents the latching lever 27 from being moved on the hinge 30 to release the tooth 31 of the latching lever from engagement with the members 23 on tape 25 so the slide can be moved. Adjacent the other end of the locking lever 20 is a detent 32 that is arranged to engage an opening 33 through the latching lever 27 and detachably hold the levers together when in a locked position.

It is obvious that when the locking lever 20 is moved from the position shown in Fig. 2 to that shown in Fig. 3 the latching lever 27 can be moved to disengage the tooth 31 from the tape; and also that when in the position shown in Figs. 1 and 2 the slide will be securely locked against accidental displacement. As it requires a noticeable manipulation to release the detent 32 from the opening 33 and turn the locking lever 20 on its pivot 28, so the fastener cannot be opened without being noticed by a person wearing a garment or carrying a purse or money bag that has this attachment connected thereto.

In operation the locking lever is normally arranged to hold the latching lever in a locked position and it is released as described.

What I claim as my invention is: y

1. A lock for a garment fastener including a slide movable to cause the interlocking members of a garment fastener to engage or disengage, a latching lever pivotally mounted on said slide, a tooth integral with said lever for engaging and disengaging the fastener passing through said slide, a locking lever pivotally mounted on said latching lever, and an extension on said locking lever arranged to contact with said slide in position to detachably hold said latching lever in a locked position.

2. In a lock for a garment fastener the combination with a slide, a latching lever pivotally connected at one end to said slide, a tooth integral with said latching lever that is movable to engage or disengage the fastener passing through said slide, of a locking lever pivotally connected between its ends to said latching lever, an extension at one end of said locking lever that is movable into and out of position to lock or release said latching lever, and a detent in the other end of said locking lever that is arranged to engage a recess in said latching lever to normally hold said lever in a locking position.
